Coordinated Cable Protection System for Harsh Conditions


Optimal Protection from Sensor to Terminal Box

Coordinated Cable Protection System for Harsh Conditions
Ensure maximum protection of your installation using our reliable cable protection system.

For many applications, safety requirements apply not only to the sensors in use but also to the cabling. To ensure that connectivity components meet these requirements, the new cable protection system from Pepperl+Fuchs offers a perfectly coordinated portfolio of sensor adapters, cable conduit, and cable glands. These components are extremely robust and designed for all standard cylindrical sensors. Regardless of the sensor you are using, you will always have the right cable protection, even for harsh environmental conditions.

Complete Solution from a Single Source

In addition to mechanical impact, pressure, and tensile strain, wiring is often exposed to chemicals. While conventional sensor cables are not usually designed to meet these demands, the new cable protection system from Pepperl+Fuchs has been specially developed for this purpose. It ensures reliable protection against malfunction in high-temperature environments or in applications that involve moving parts. Along with cable protection, we also offer the right sensor and suitable terminal box as a complete solution from a single source.

The sensor adapter provides a solid connection between the cylindrical sensor and the flexible conduit. It can be easily screwed onto the cylindrical sensor. With M8, M12, M14, M18, and M30 sizes available, Pepperl+Fuchs offers an adapter for every standard cylindrical sensor in its portfolio.

As a key component of the cable protection system, the flexible conduit seals the cable from the sensor to the terminal box. Depending on your application requirements, it is available in a corrosion-resistant metal version or in a coated version with IP67 protection to shield the cable from substances such as oil and grease.

The cable gland connects the flexible conduit with the terminal box and is available in M12, M16, and M30 thread sizes. The inner seal prevents liquid and dust from entering the interior of the terminal box.

Versatile Applications

The new cable protection system is mainly used in machine engineering as well as in the chemical and petrochemical industries. It is often part of a complete solution, like one that was recently developed in cooperation with a valve manufacturer to detect four individual positions of a control valve.

Two or four inductive cylindrical sensors are used, along with the new cable protection system and the terminal box, which contains all wiring. This completely coordinated solution can be adapted to all common valve types and enables reliable valve control, even in extremely harsh conditions.
